ares_parse_aaaa_reply

NAME

ares_parse_aaaa_reply - Parse a reply to a DNS query of type AAAA

SYNOPSIS

#include <ares.h>

int ares_parse_aaaa_reply(const unsigned char *abuf, int alen, struct hostent **host, struct ares_addr6ttl *addrttls, int *naddrttls);

DESCRIPTION

The ares_parse_aaaa_reply function parses the response to a query of type AAAA into a struct hostent and/or an array of struct ares_addr6ttl . The parameters abuf and alen give the contents of the response. The result is stored in allocated memory and a pointer to it stored into the variable pointed to by host , if host is nonnull. It is the caller's responsibility to free the resulting host structure using ares_free_hostent (3) when it is no longer needed.

If addrttls and naddrttls are both nonnull, then up to *naddrttls struct ares_addr6ttl records are stored in the array pointed to by addrttls, and then *naddrttls is set to the number of records so stored. Note that the memory for these records is supplied by the caller.

RETURN VALUES

ares_parse_aaaa_reply can return any of the following values:

ARES_SUCCESS The response was successfully parsed.

ARES_EBADRESP The response was malformatted.

ARES_ENODATA The response did not contain an answer to the query.

ARES_ENOMEM Memory was exhausted.
